- We are trying to use ParaView on a cluster without GPUs, so that we had to install OSMesa library (version 7.0.3-7) as explained here:

http://www.itk.org/Wiki/Setting_up_a_ParaView_Server#X_Connections

- Open MPI 1.2.7rc2



>Does this happen when running locally

No, it doesn't.
I tried to run the client and the server on my computer and it works.

> when running 1 server node?

Yes, it does. I tried to run the client and the server on the master node of the cluster: the error occurs when we push the button "apply"
(after establishing the connection between client and server and after loading a file)

We run the test in the /home/utente/ParaView-bin directory.
We did make install.

VTK_USE_RPATH = OFF (default, I believe)

How LD_LIBRARY_PATH has to be set? On each node?
Have we to install rpath on each node of the cluster?

If you need more information, please let me know.
Than you very much
